How does Nicole Murphy stay bikini-ready? The 5'11" model, mother of five and star of VH1's Hollywood Exes
works out almost daily and has a diet regimen complete with a daily sweet splurge.
In PEOPLE's special Most Talked About Bodies
issue, Murphy, 46, admits she keeps a cookie jar filled with 365 brand sandwich cookies from Whole Foods and treats herself to a couple of them mid-morning.
And she's not afraid to share her other favorite sweet spots: "I love the oatmeal raisin cookie at Urth Caffé," she admits. "I also absolutely love the pistachio, chocolate or vanilla macarons from Monsieur Marcel
Murphy's fiancé Michael Strahan
, 42, shares her love for sugary snacks. He told PEOPLE
this spring, "I have the biggest sweet tooth! You name it, I will eat it!"
To counter the desserts, Murphy rotates between cardio kickboxing classes with trainer Natalie Yco
, circuit training, hiking and yoga weekly, and tries to get some exercise in daily. And every time she hits the gym she focuses on one key asset: "I always begin with glute isolation exercises like butt kicks," she says.
And even when she allows herself one cheat meal a week, Murphy doesn't go calorie crazy. "I love the burgers at the South Beverly Grill," she says. "Even though it's my cheat meal, I still try to aim healthy by having my burger wrapped in lettuce and I order a small side of sweet potato fries – that makes me feel less guilty!"
